Application filed October 2, 1905. Serial No. 281,034.

To all whom it may concern.-

Be it known that I, ZEDDIE L. HARBIN, a citizen of the United States, residing at Canton, in the county of Haywood, State of North Carolina, have invented certain new and useful Improvements in Churns; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to churns.

One object of the invention is to provide an exceedingly simple, inexpensive, durable, and efficient churn wherein a number of dashers cooperate in the churning action.

Another object of the invention resides in the provision of a churn wherein a plurality of dashers cooperate with one another in the churning action, the dashers being arranged upon alining shafts within the body of the churn, the handle or crank for operating the dashers being journaled directly in the side of the said body and communicating with the dasher-shafts through the instrumentality1 of gear-wheels and single short shaft or roc.

With these and other objects in view the present invention consists in the combination and arrangement of parts, as will be hereinafter more fully described, shown in the accompanying drawings, and particularly pointed out in the appended claim, it being understood. that changes in the form, proportion, size, and minor details may be made within the scope of the claim without departing from the spirit or sacrificing any of the advantages of the present invention.

In the drawings, Figure 1 is an elevation of my invention, parts being shown in section. Fig. 2 is a detail perspective view of the short shaft-supporting bracket. Fig. 3 is a detail perspective view of the crankhandle-supporting bracket. Fig. 4 shows a modification illustrating a different arrangement of dashers.

Referring now more particularly to the accompanying drawings, the reference character 1 designates the body of the churn, having a cover 2 at its upper end resting upon the cleat 3, arranged interiorly of the body to permit of the contents being removed or placed within the body of the churn for churning purposes. This body portion may i be of cylindrical form, as shown, or obviously of any other formation. Alining journalbearings 4 are disposed upon the upper face of the bottom 5 of the body portion of the churn for the reception of the lower ends of the corresponding dasher-shafts 6 and 7, whose upper ends extend through corresponding perforations in the body of the cover 2, the upper protruding ends of the said shafts having gear-wheels 8 and 9 secured, respectively, thereto.

Secured to one side of the body portion of the churn by means of a suitable fastening 10 is an outwardly-extending bracket 11, of sheet metal or other suitable material, hav ing an eye in its outer free end forming a bearing 12. Formed in the body of the churn is a recess or bearing 13, which alines with the bearing 12 of the bracket 11, which bearings receive the shaft portion 14 of the crank-handle 15, there being a pair of wash ers or the like 16 disposed upon the portion 14 of the crank-handle 15 upon opposite sides of the perforation or bearing 12 of the bracket 11, whereby the inner end of the portion 14 of the handle is prevented from leaving the recess or bearing 13 in the side of the body 1. It will be observed that the bushing or journal-bearing 13 does not eX- tend entirely through the body, but extends only a slight distance into the wall thereof, as clearly shown in the drawings, and therefore it will be understood that the washerplates 16 serve to prevent accidental displacement of the inner end of the portion 14 of the handle with respect to its journal bearing 13. Of course these washer-plates do not fit against the bracket so tightly as to prevent proper rotation of the crank-handle.

FiXedly mounted upon the portion 14 of the handle adjacent the body 1 is a beveled gear-wheel 17, designed to mesh with the beveled gear-wheel 18, carried at the lower end of the short shaft 19, at the upper end of which latter is a pinion 20, designed to mesh with the gear-wheel 9 at the upper end of the dasher-shaft 7, which latter gear-wheel is in mesh with the gear-Wheel 8 of the dashershaft 6. The short shaft 19 is held in vertical position by the bracket 21, secured in any suitable manner to the body 1 between the beveled gear-wheel 18 and the pinion 20, the said bracket having spaced alining eyes 22 and 28, in which the short shaft 19 rotates,

the latter having two shoulders 24 and 25, which rest upon the eyes 22 and 23 of the last-named bracket, preventing accidental dropping or other displacement of the shaft, as well understood. It is obvious that instead of the peculiarly-formed bracket 21 two short arms 21" and 21*, each having an eye therein at its end, may be employed, as shown in the dotted lines in Fig. 1.

Secured at intervals by means of set-screws or the like 26 upon each of the respective dasher-shafts 6 and 7 is a series of dashers 27 and 28. Each shaft 6 and 7 has a series of collars A and B, respectively, each of which is provided with a screw-threaded perforation (1. These dashers each include two members 27 and 27 and 28 and 28 respectively, each of the members crossing its companion at an acute angle to the plane of the respective shaft, there being provided a perforation 29 at the intersection of the said members of each dasher for the reception of the corresponding set-screw 26, which works in the correspondingly-threaded perforation 29 of the dashers and the perforation a of the corresponding collars to clamp the dashers upon the shafts. By reason of this mounting of the dashers upon the shaft each dasher may be adjusted independently of another dasher upon its corresponding shaft, and whereby one member of the dasher may be arranged to pass between members of the dasher mounted upon the opposite shaft or whereby corresponding members of one dasher may rotate in the same plane as the corresponding members of the opposite dasher.

From the foregoing it will be understood that when the crank-handle is operated the beveled. gear 17 is caused to rotate, which being in mesh with the beveled gear 18 causes the short shaft 19 to rotate, and with it the pinion 20, which meshes with the gear-wheel 9, which latter meshing with the gear-wheel 8 causes the latter to rotate in the direction opposite tothe direction of rotation of the gear-wheel 9, permitting the dasher-shafts 6 and 7 to rotate in opposite direction one with respect to the other. 1

When it is desired to remove the contents from the churn, it is only necessary to lift the cover 2 from the body, carrying with it the shafts and the dashers and also the gearwheels 8 and 9, it being understood that the lower ends of the dasher-shafts can be readily replaced in their seats or bearings in the bottom of the body when desired.

What is claimed is A churn comprising a body portion including a cover, a pair of shafts journaled in the bottom of the body and its cover and protruding through the latter, a gear-wheel carried on the protruding end of each shaft, the gear wheels meshing with each other, a bracket connected to the said body and having a journal bearing in its outer end, a bearing formed in the body and in direct alinement with the bearing of the said bracket, a crank-handle journaled in the said bearings, the crankshaft carrying a beveled gear, a short vertical shaft mounted upon the body of the churn and having a beveled gear at its lower end for mesh with the beveled gear of the handle and a pinion at its upper end for mesh with one of the aforesaid gear-wheels of the shafts, and dashers adjustably mounted upon, the said shaft.

In testimony whereof I affix my signature in presence of two witnesses.

ZEDDIE L. HARBIN.
